These Scalloped Potatoes feature the tastiest sauce, ever! Layers of thinly cut potatoes, parmesan cheese and a deliciously creamy sauce make up this must have side dish.
I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Preheat an oven to 350° F and lightly grease an 8x8 baking dish.
In a medium saucepan over medium heat add in the olive oil. Once hot add in the butter and onions. Sauté for 5 minutes, or until translucent. Now add in the minced garlic and sauté for 30 seconds.
Whisk in the flour to make the roux, cook for 1 minute.
Slowly whisk in the milk. Whisk until the roux is fully incorporated, then whisk in the chicken stock. Continue cooking over medium-low heat until the sauce has thickened. Season with salt and pepper to taste. Set aside.
Layer half of the sliced potatoes in the prepared baking dish. Sprinkle with ⅓ cup of cheese and some of the fresh thyme. Pour half of the sauce over the potatoes in an even layer.
Repeat the layering again. Now sprinkle the top layer of sauce with the remaining cheese. Cover with foil. Reserve the some of the fresh thyme for garnishing.
Bake for 30 minutes, or until bubbly. Remove the foil and bake for another 30 minutes. Turn the oven to broil for 2 minutes to brown cheese if desired. Garnish with thyme. Enjoy!
